It's available hear in the UK from Hobby shop's and DIY stores. It's very similar to clear laquer spray but dries frosty when sprayed onto a glass surface. LED's as you know have a projected light so frosting spray gives a more even spread of light around the glass body. I'll try and find my can out and see if there is a Web address if your'e interested.

Thanks crowclaw,
I found enough info.
In the states, rustoleum make this kind of paint.
The acrylic glow paint I tried last year did make the led safer to my eyes, but I do not think it spread the light like a good diffuser.
So, a thrift store drinking glass painted with this spray frost on the inside might work well.

@All,

I did a lot of experimenting with diffusers about 6 years ago.

I had made some single orange colored led candles.
They were rated at k mcd, so a simple calculation told me this was rated at the equivalent of 9 candles.
NOT EVEN CLOSE!

These were made with 2AAA batteries a 47 ohm resistor and a push switch and , of course, the single led.

I tried a lot of things then I literally lit a candle.
I saw that much of what lights the room from the candle is the hot pool of wax and to some extent the entire candle, because all of it glows a little.

In my video I showed my very effective and very cheap overturned plastic cup.

But the real discovery was a kind of paper called vellum.
There are different qualities and your stationery store may have a good one..I hope.

I made a variety of tubes to surround the single led and found that the 1 inch long tube made less light than the 11 inch tube. I made a tube with a 3 inch diameter by 5 inch length. That worked great too. And when I added the overturned plastic cup on the top of this long and fat tube, it added another 4 1/2 inches to the glow of the candle.

Last week after I made the video of the globe light with 24 leds, I surrounded the lights with a tube of vellum inside the globe. This worked well. This light fills the room better and with more light than the cfl. (But without the paper it is a bunch of spots and not as good.)

I agree. I am sure that they are only gold plated and not worth much. A trip to the jewelers is good advice.
